Why does the keyboard and/or palm rest get warm?
Typically, the Joybook tends to be slightly warm. The location of the hard
disk is typically underneath the palm rest and as a result, the palm rest
gets warm. The location of the processor is typically underneath the
keyboard and since heat rises, the keyboard may slightly get warm. There
is no need to be concerned. However, since your computer has a
thermally controlled fan, when the CPU and/or internal temperature of
the notebook reaches a certain temperature level, the fan is turned ON
and stays ON until the temperature drops to a pre-defined level.
The U, I, O, P, J, K, L keys on my Joybook are coming up as numbers

normal.
